Abstract

Two new species of Barbacenia (Velloziaceae) from the Brazilian campo rupestre from the southern part of the Espinhaço Range are here described and illustrated. Both new species, Barbacenia glaucescens Ferreira-Junior & Andr.Cabral sp. nov. and B. mellosilvae Andr.Cabral & Ferreira-Junior sp. nov., resemble B. gentianoides Taub. ex Goethart & Henrard, and the second one also resembles B. longiflora Mart. However, both can be differentiated by a unique combination of morphological and anatomical characters. Morphological and anatomical descriptions, illustrations, photographs, phenological information, provisional risk assessments, distribution map, and taxonomic notes are provided for the new species.
